2016-12-14 4.3.0 Safety

New Features

  • Unlink and Link Packages in a Single Transaction: In the past, conda hasn’t always been safe and defensive with its disk-mutating actions. It has gleefully clobbered existing files, and mid-operation failures leave environments completely broken. In some of the most severe examples, conda can appear to “uninstall itself.” With this release, the unlinking and linking of packages for an executed command is done in a single transaction. If a failure occurs for any reason while conda is mutating files on disk, the environment will be returned its previous state. While we’ve implemented some pre-transaction checks (verifying package integrity for example), it’s impossible to anticipate every failure mechanism. In some circumstances, OS file permissions cannot be fully known until an operation is attempted and fails. And conda itself is not without bugs. Moving forward, unforeseeable failures won’t be catastrophic. (#3833, #4030)

  • Progressive Fetch and Extract Transactions: Like package unlinking and linking, the download and extract phases of package handling have also been given transaction-like behavior. The distinction is the rollback on error is limited to a single package. Rather than rolling back the download and extract operation for all packages, the single-package rollback prevents the need for having to re-download every package if an error is encountered. (#4021, #4030)

  • Generic- and Python-Type Noarch/Universal Packages: Along with conda-build 2.1.0, a noarch/universal type for python packages is officially supported. These are much like universal python wheels. Files in a python noarch package are linked into a prefix just like any other conda package, with the following additional features:

    1. conda maps the site-packages directory to the correct location for the python version in the environment,
    2. conda maps the python-scripts directory to either $PREFIX/bin or $PREFIX/Scripts depending on platform,
    3. conda creates the python entry points specified in the conda-build recipe, and
    4. conda compiles pyc files at install time when prefix write permissions are guaranteed.

    Python noarch packages must be “fully universal.” They cannot have OS- or python version-specific dependencies. They cannot have OS- or python version-specific “scripts” files. If these features are needed, traditional conda packages must be used. (#3712)

  • Multi-User Package Caches: While the on-disk package cache structure has been preserved, the core logic implementing package cache handling has had a complete overhaul. Writable and read-only package caches are fully supported. (#4021)

  • Python API Module: An oft requested feature is the ability to use conda as a python library, obviating the need to “shell out” to another python process. Conda 4.3 includes a conda.cli.python_api module that facilitates this use case. While we maintain the user-facing command-line interface, conda commands can be executed in-process. There is also a conda.exports module to facilitate longer-term usage of conda as a library across conda conda releases. However, conda’s python code is considered internal and private, subject to change at any time across releases. At the moment, conda will not install itself into environments other than its original install environment. (#4028)

  • Remove All Locks: Locking has never been fully effective in conda, and it often created a false sense of security. In this release, multi-user package cache support has been implemented for improved safety by hard-linking packages in read-only caches to the user’s primary user package cache. Still, users are cautioned that undefined behavior can result when conda is running in multiple process and operating on the same package caches and/or environments. (#3862)

Deprecations/Breaking Changes

  • Conda now has the ability to refuse to clobber existing files that are not within the unlink instructions of the transaction. This behavior is configurable via the path_conflict configuration option, which has three possible values: clobber, warn, and prevent. In 4.3, the default value will be clobber. That will give package maintainers time to correct current incompatibilities within their package ecosystem. In 4.4, the default will switch to warn, which means these operations continue to clobber, but the warning messages are displayed. In 4.5, the default value will switch to prevent. As we tighten up the path_conflict constraint, a new command line flag –clobber will loosen it back up on an ad hoc basis. Using –clobber overrides the setting for path_conflict to effectively be clobber for that operation.
  • Conda signed packages have been removed in 4.3. Vulnerabilities existed. An illusion of security is worse than not having the feature at all. We will be incorporating The Update Framework into conda in a future feature release. (#4064)
  • Conda 4.4 will drop support for older versions of conda-build.

2016-07-28 4.2.0

New Features

  • New Configuration Engine: Configuration and “operating context” are the foundation of conda’s functionality. Conda now has the ability to pull configuration information from a multitude of on-disk locations, including .d directories and a .condarc file within a conda environment), along with full CONDA_ environment variable support. Helpful validation errors are given for improperly-specified configuration. Full documentation updates pending. (#2537, #3160, #3178)
  • New Exception Handling Engine: Previous releases followed a pattern of premature exiting (with hard calls to sys.exit()) when exceptional circumstances were encountered. This release replaces over 100 sys.exit calls with python exceptions. For conda developers, this will result in tests that are easier to write. For developers using conda, this is a first step on a long path toward conda being directly importable. For conda users, this will eventually result in more helpful and descriptive errors messages. (#2899, #2993, #3016, #3152, #3045)
  • Empty Environments: Conda can now create “empty” environments when no initial packages are specified, alleviating a common source of confusion. (#3072, #3174)
  • Conda in Private Env: Conda can now be configured to live within its own private environment. While it’s not yet default behavior, this represents a first step toward separating the root environment into a “conda private” environment and a “user default” environment. (#3068)
  • Regex Version Specification: Regular expressions are now valid version specifiers. For example, ^1\.[5-8]\.1$|2.2. (#2933)

2016-06-14 4.1.0:

This release contains many small bug fixes for all operating systems, and a few special fixes for Windows behavior.

Notable changes for all systems (Windows, OS X and Linux)

  • Channel order now matters. The most significant conda change is that when you add channels, channel order matters. If you have a list of channels in a .condarc file, conda installs the package from the first channel where it’s available, even if it’s available in a later channel with a higher version number.
  • No version downgrades. Conda remove no longer performs version downgrades on any remaining packages that might be suggested to resolve dependency losses; the package will just be removed instead.
  • New YAML parser/emitter. PyYAML is replaced with ruamel.yaml, which gives more robust control over yaml document use. More on ruamel.yaml
  • Shebang lines over 127 characters are now truncated (Linux, OS X only). Shebangs are the first line of the many executable scripts that tell the operating system how to execute the program. They start with #!. Most OSes don’t support these lines over 127 characters, so conda now checks the length and replaces the full interpreter path in long lines with /usr/bin/env. When you’re working in a conda environment that is deeply under many directories, or you otherwise have long paths to your conda environment, make sure you activate that environment now.
  • Changes to conda list command. When looking for packages that aren’t installed with conda, conda list now examines the Python site-packages directory rather than relying on pip.
  • Changes to conda remove command. The command conda remove --all now removes a conda environment without fetching information from a remote server on the packages in the environment.
  • Conda update can be turned off and on. When turned off, conda will not update itself unless the user manually issues a conda update command. Previously conda updated any time a user updated or installed a package in the root environment. Use the option conda config set auto_update_conda false.
  • Improved support for BeeGFS. BeeGFS is a parallel cluster file system for performance and designed for easy installation and management. More on BeeGFS

Windows-only changes

  • Shortcuts are no longer installed by default on Windows. Shortcuts can now be installed with the --shortcuts option. Example 1: Install a shortcut to Spyder with conda install spyder --shortcut. Note if you have Anaconda (not Miniconda), you already have this shortcut and Spyder. Example 2: Install the open source package named console_shortcut. When you click the shortcut icon, a terminal window will open with the environment containing the console_shortcut package already activated. conda install console_shortcut --shortcuts
  • Skip binary replacement on Windows. Linux & OS X have binaries that are coded with library locations, and this information must sometimes be replaced for relocatability, but Windows does not generally embed prefixes in binaries, and was already relocatable. We skip binary replacement on Windows.

    —no-update-deps: conda will update the packages only to the extent that no updates to the dependencies are required

    The previous behavior, which would update the packages without regard to their dependencies, could result in a broken configuration, and has been removed.

  • use the trash in rm_rf, meaning more things will get the benefit of the trash system on Windows
  • add the ability to pass the –file argument multiple times
  • add conda upgrade alias for conda update
  • add update_dependencies condarc option and –update-deps/–no-update-deps command line flags
  • allow specs with conda update –all

  • print which file leads to the “unable to remove file” error on Windows
  • add support for the no_proxy environment variable, #1171
  • add a much faster hint generation for unsatisfiable packages, which is now always enabled (previously it would not run if there were more than ten specs). The new hint only gives one set of conflicting packages, rather than all sets, so multiple passes may be necessary to fix such issues
  • conda extensions that import conda should use conda.cli.conda_argparser.ArgumentParser instead of argparse.ArgumentParser to conform to the conda help guidelines (e.g., all help messages should be capitalized with periods, and the options should be preceded by “Options:” for the sake of help2man).

  • allow paths in has_prefix to be quoted, to allow for spaces in paths on Windows
  • retain Linux/macOS style path separators for prefixes in has_prefix on Windows (if the placeholder path uses /, replace it with a path that uses /, not \)
  • fix bug in –use-local due to API changes in conda-build
  • include user site directories in conda info -s

  • add –alt-hint as a method to get an alternate form of a hint for unsatisfiable packages
  • add conda package –ls-files to list files in a package
  • add ability to pin specs in an environment. To pin a spec, add a file called pinned to the environment’s conda-meta directory with the specs to pin. Pinned specs are always kept installed, unless the –no-pin flag is used.

  • add ability to disable self update of conda, by setting “self_update: False” in .condarc
  • Try installing packages using the old way of just installing the maximum versions of things first. This provides a major speedup of solving the package specifications in the cases where this scheme works.
  • Don’t include python=3.3 in the specs automatically for the Python 3 version of conda. This allows you to do “conda create -n env package” for a package that only has a Python 2 version without specifying “python=2”. This change has no effect in Python 2.
  • Automatically put symlinks to conda, activate, and deactivate in each environment on Linux and macOS.
  • On Linux and macOS, activate and deactivate now remove the root environment from the PATH. This should prevent “bleed through” issues with commands not installed in the activated environment but that are installed in the root environment. If you have “setup.py develop” installed conda on Linux or macOS, you should run this command again, as the activate and deactivate scripts have changed.
  • Begin work to support Python 3.4.
  • Fix a bug in version comparison
  • Fix usage of sys.stdout and sys.stderr in environments like pythonw on Windows where they are nonstandard file descriptors.

  • print dots to the screen for progress
  • move logic functions from resolve to logic module

2014-03-07 3.2.0a1:

  • conda now uses pseudo-boolean constraints in the SAT solver. This allows it to search for all versions at once, rather than only the latest (issue #491).
  • Conda contains a brand new logic submodule for converting pseudo-boolean constraints into SAT clauses.

2014-03-07 3.1.1:

  • check if directory exists, fixed issue #591

2014-03-07 3.1.0:

  • local packages in cache are now added to the index, this may be disabled by using the –known option, which only makes conda use index metadata from the known remote channels
  • add –use-index-cache option to enable using cache of channel index files
  • fix ownership of files when installing as root on Linux
  • conda search: add ‘.’ symbol for extracted (cached) packages

2014-02-20 3.0.6:

  • print the total download size
  • fix a bug that was preventing conda from working in Python 3

  • removed build, convert, index, and skeleton commands, which are now part of the conda-build project: https://github.com/conda/conda-build
  • limited pip integration to conda list, that means conda install no longer calls pip install # !!!
  • add ability to call sub-commands named ‘conda-x’
  • The -c flag to conda search is now shorthand for –channel, not –canonical (this is to be consistent with other conda commands)
  • allow changing location of .condarc file using the CONDARC environment variable
  • conda search now shows the channel that the package comes from
  • conda search has a new –platform flag for searching for packages in other platforms.

  • add ability create info/no_softlink
  • add conda convert command to convert non-platform-dependent packages from one platform to another (experimental)
  • unify create, install, and update code. This adds many features to create and update that were previously only available to install. A backwards incompatible change is that conda create -f now means –force, not –file.

2014-01-16 2.3.0:

  • automatically prepend http://conda.binstar.org/ (or the value of channel_alias in the .condarc file) to channels whenever the channel is not a URL or the word ‘defaults or ‘system’
  • recipes made with the skeleton pypi command will use setuptools instead of distribute
  • re-work the setuptools dependency and entry_point logic so that non console_script entry_points for packages with a dependency on setuptools will get correct build script with conda skeleton pypi
  • add -m, –mkdir option to conda install
  • add ability to disable soft-linking

2014-01-06 2.2.8:
